JOHN T. FARRELL, OF HOUSTON, TEXAS.

To all 1127; omit may concern:

Be it known that 1, JOHN T. FARRELL; citizen of the United States,residing at Houston, in the county of Harris and State of Texas, haveinvented certain new and useful Improvements in Derailers, of which thefollowing is a specification.

My invention relates to new and useful improvements in derailers.

The object of the invention is to provide a superior derailer of simpleconstruction which may be operated from a switch stand if desired orlocked on the rail.

Another object is to provide a device of the character described thatwill be strong, durable, efficient and simple and comparativelyinexpensive to construct, also one in which the several parts will notbe liable to get out of working order.

\Vith the above and other objects in view, the invention has relation tocertain novel features of construction and operation, an example ofwhich is described in the following specification and illustrated in theaccompanying drawings, wherein:

Figure 1 is a plan view of the derailer and a portion of the track, Fig.2 is a side elevation of the same, Fig. 3 is a transverse section of thederailer block, Fig. a is an end view of the parts shown in Fig. 1, Fig.5 is an inside elevation of the derailing block, Fig. 6 is a plan Viewof the bracket, and Fig. 7 is a rear elevation of the same.

In the drawings the numeral 1 designates an ordinary rail supported onthe ties 2. To the outer side of the web 3 a bracket 1 is secured by asuitable bolt 5 so as to project horizontally toward the inside of thetrack. This bracket is formed with side arms 6 and a pocket 7 shaped tosnugly receive and fit the outer base flange of the rail.

Between the side arms 6 a derailing block 8 is pivotally mounted on abolt 9, the said bolt passing through one ofa plurality of openings 10in each side arm which permits the said block to be adjusted verticallyto accommodate different heights of rails and 4 laterally to accommodatedifferent formations of rail treads such as an L formation. This blockis curved upwardly and formed with a shoe portion 11 which rests on therail 1 and projects over the same at 12 where it slopes down toward theoutside of the track, while at its opposite end 13 it slopes down towardthe inside of the rail.

The shoe portion has a diagonal groove or channel 14 which begins insideof the head of the rail and ends outside of the same. The groove 14 andthe block are properly shaped so that.the flange of the wheel will rideinto the groove and be guided across to the outside of the rail and thederailing properly carried out. The block is provided with a projection15 adjacent the groove against which the flange of the wheel will strikeand be thrown toward the rail as it leaves the block.

At its lower end, the block is provided with a slotted opening 16 toreceive a suitable connection from a switch stand by which the block,being pivotally mounted, may be swung on to the rail or raised oil ofthe same and thrown back when it is not desired to use the derailer. Aneye 17 is provided on the shoe 11 to receive a locking key 18, one endof which is secured to a chain 19 having suitable connection with one ofthe track bolts. By this arrangement the block may be locked intoposition when it is desired to use it permanently on the rail, as at theend of a siding.

I wish to call particular attention to the fact that the block 8 ispivoted some distance above its lower end which permits it to be readilyswung off of the rail when it is not desired to use it and to be throwndown on to the rail whenever desired. By arranging it to be connected toa switch stand it may be locked in or out of operating position just thesame as an ordinary switch tongue.

What I claim, is:

1. In a derailer, the combination with a rail, of a bracket secured tothe rail and provided with side arms having a plurality of boltreceiving openings, a grooved block disposed between the side arms, anda bolt passing through one of the openings in each side arm and theblock for pivotally and adjustably supporting the same.

2. A derailer of the character described comprising supporting meansadapted to be located adjacent to a rail, a block 8 pivoted to saidsupport adapted to rest upon a rail having the shoe portion 11 and theprojection 15 arranged substantially as and for the purpose described.

3. A derailer of the character described comprising a support adapted tobe mounted 1 adjacent to a rail, a block 8 pivoted to said support, andmeans adapted to connect the block and the rail for fastening the blockagainst removal from the tread.

4. A derailer of the character described comprising a support formed toembrace one of the base flanges of a rail, means adapted to engage theWeb of a rail and said support for fastening the same in place, and ablock 8 pivoted to the support adapted to rest upon the tread of therail substantially as and for the purpose described.

5. A derailer of the character described comprising a support adapted tobe mounted adjacent to a rail, a block 8 adapted to rest upon the treadof a rail, and means whereby 15 the block may be bodily adjusted todifferent positions relative to and pivoted to the support substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of 20 two subscribing Witnesses.

JOHN T. FARRELL.
